This research aims to examine how much impact social media channels have on stock returns during unusual market events. We do this by measuring the sentiment and activity on the Reddit forum wallstreetbets (WSB) regarding some of the six most mentioned companies during the first four months of 2021 and connect this to their relative stock returns. The sentiment is derived through a sentiment analy

Denna kvalitativa intervjustudie syftar till att undersöka hur arbete med sociala medier påverkar kommunikatörers arbetssituation samt att utforska strategier för att möjliggöra ett kommunikativt uppdrag som kan upplevas som påfrestande för individen. Genom djupintervjuer med praktiserande kommunikatörer visar studien hur arbete med sociala medier leder till en sammanblandning av den privata och pThis qualitative interview study aims to investigate how working with social media affects communication practitioners’ work situations. Moreover, it explores strategies for facilitating a communicative mission that may be perceived as stressful for the individual. Through in-depth interviews with communication practitioners, this study shows how working with social media leads to a merge of the p

Bakgrund: Barnmorskors upplevelser av att själva föda barn är ett relativt outforskat område. Befintlig forskning berör övrig vårdpersonals upplevelser av att vara patient. I Sverige sker de flesta förlossningar på sjukhus och en majoritet av alla yrkesverksamma barnmorskor är kvinnor. Detta innebär att många barnmorskor någon gång kommer att befinna sig i situationen som födande patient eller som

Framtidens kliniska prövningar - Konceptualisering av ett decentraliserat digitalt system Tolv år och 1336 miljoner dollar, det är vad som krävs i genomsnitt för att framställa ett nytt läkemedel. För att kunna erbjuda alla människor så bra behandling som möjligt skulle det skulle därför vara fördelaktigt om processen kunde effektiviseras och ett viktigt steg i att få en ny behandling godkänd ärDeveloping and getting a new medicine approved is a long and expensive process and it would therefore be beneficial if it could be streamlined. In order to control the effect and safety of a new treatment, clinical trials are performed. Traditionally, these have been performed at physical clinics, but with digitalization the option to collect clinical data remotely has been presented. This thesi

The aim of this study is to analyze the differences in years of education for men and women, and how these differences affect economic growth. The author believes there is a significant loss of human capital in the world, when girls for different reasons do not reach the same level of education as boys. This loss becomes clear by inspecting the literacy rate for each gender, and when viewing the o

The main objective of this paper is to investigate price determining factors in Swedish grocery retailing. By combining economic theory with linear regression analysis the paper wishes to shed light on what kind of factors that are affecting Swedish food retailers when they are pricing food products. Different food retailers face different conditions when it comes to competition, demand, locality

In recent years, Kate Raworth’s new alternative macroeconomic model, “doughnut economics” (DE) has become increasingly popular within policies on different scales around the world. The doughnut-shaped framework addresses the urgent crises of our time by advocating for a balanced development that considers the planet’s well-being while securing our social needs. Since the introduction of the framew

This thesis set out to map the relation Swedish farmers have to their occupation and production, while also investigating what challenges farmers experience which in turn might affect social sustainability in Swedish agriculture negatively. Agriculture was approached as a case of low social sustainability based on the fact that more than one-third of Swedish farmers are over retiring age, while yo

Preterm birth is a leading cause for birth complications and neonatal mortality in the world. It remains difficult to predict whether a preterm birth will occur, which hinders the possible use of prevention treatments. This thesis investigates the use of machine learning models in the prediction of spontaneous preterm birth. In addition, possible heterogeneous performance of these models among dif

In this essay I will be studying the effects of border control on Sweden’s international trade, using the gravity model and a fixed effects method. The gravity model is one of the empirically most successful tools in the field of international economy today. But it is also a tool which relies on the literature and previous research for its theoretical foundation. The regression used in this essay

Bakgrund: Förekomsten av utmattningssyndrom (UMS) ökar i Sverige, vilket leder till allt längre sjukskrivningstider. En längre period med höga nivåer av stress i kombination med otillräcklig återhämtningkan leda till utvecklandet av UMS. Syndromet kännetecknas av tre aspekter: känsla av utmattning, mental distansering och minskad effektivitet. Att vara drabbad av UMS ökar risken för tveckling av e

Bakgrund: Ocklusion, på engelska benämnt som blood flow restriction (BFR), innebär att man placerar exempelvis en blodtrycksmanschett proximalt på en extremitet, stryper åt och minskar blodflödet till en muskelgrupp. I kombination med lågbelastad styrketräning kan det inducera styrkeökning. Vid ACL-skada, knäartros och andra knätillstånd är styrketräning en stor del av rehabiliteringen där målet f

The Department of Automatic Control at Lund University annually gives a project course in Automatic Control (FRTN40). The course is given at the advanced level (7.5 ECTS credits), and the students work in small teams to achieve a common goal. The projects typically involve a real-world estimation or control problem with relevance to industrial or other applications. In this course, the students ge

Bakgrund: Främre korsbandsskador är en av de vanligaste skadorna inom idrottsskadetraumatologin. Detta är ett bekymmer då det främre korsbandet är en av de viktigaste stabiliserande strukturerna i knäleden. Vid en skada förlorar idrottaren således mycket av knäledens stabilitet och neuromuskulära kontroll, vilket ofta ger långsiktiga negativa konsekvenser såsom instabilitet och artros. Det finns f

There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. The classifier used hyperspectral images in infrared of four

Let (G, g) be a 4-dimensional Riemannian Lie group with a 2-dimensional left-invariant, conformal foliation with minimal leaves. Let J be an almost Hermitian structure on G adapted to the foliation. The corresponding Lie algebra must then belong to one of 20 families according to S. Gudmundsson and M. Svensson. We classify such structures J which are almost Kähler, integrable or Kähler. Hereby, we

Situated in Geneva, Switzerland, the Large Hadron Collider is largest particle accelerator in the world, and as such, its operation carries with it some of the greatest technical challenges ever faced. Among them are the huge demands put on data storage capacity by experiments in particle physics, both in terms of rate and volume of data. Several systems are employed to manage and reduce the flow
